Application of conductometric and pH metric measurements in determining the kinetics and equilibrium parameters of the heterophasic ion exchange: Met…
2019
The application possibilities of conductometric and pH metric measurements in the description of the process of heterophasic ion exchange have been analysed, between metal cation (Zn, Cu) - proton, which occurs according to the formula, M+ + HR ⇄ H+ + MR, where R is an anion permanently bound in the sorbent. Kinetic models of the pseudo-first and pseudo-second order reactions, as well as the Langmuir isotherm model which describes the process equilibrium, have been used in mathematical presentations. It was confirmed that conductometric and pH metric measurements are equally effective in the assessment of such processes' parameters, in comparison with the expensive method of determining met…
